The theme for tonight’s Youth for Christ campus life meeting is “Living in the Moment,” and that’s certainly what the 50 Bloomington high schoolers are doing. Divided equally into four groups — each group bound together by a rope — they’re romping across a massive yard like puppies on a playground. The game is called “group tag,” and as a cluster of boys chases a bunch of screaming girls, the females trip and collapse onto the lawn in a pitiful heap. Moments later, the youngsters are sitting on the grass in small groups — each with an adult leader — discussing what “living in the moment” means to them.
